IMPROVI- IMENT INMACHINES FOR TURNING IRREGULAR FORMS.

Specification forming part of Letters Patent No. 36.093. dated August 5, 1862.

To all whom it may concern:

Be it. known that we, A. B. HENDRYX, of Seymour, in the county of New Haven and State of Connecticut, and FRANKLIN FARRELL,

of Ansonia, in the same county and State,hav e invented a new and Improved Machine for Turning Irregular Forms,the same being more especially designed for-turning the necksof bayonets; and we do hereby declare that the.

opviewdfithe same;..Fig. 3, a transverse. vers.

tical section of the same,taken in the line 3 y,

Fig. 1 Fig. 4, a detached view of a bayonet.

Similar letters of reference indicate corresponding parts in the several figures.

' I This invention consists in the employment oruse of a rotary adjustable cutter, a sliding pattern, and a movable stock or bed piece arranged in-such a mann'er that articles having curved surfaces intheir longitudinal profiles,

or straight and curved surfaces combined, may

be expeditiously turned in a perfect manner,

To enable those skilled in the art to fully understand and construct our invention, We will proceed to describe it.

. A represents the bed of thelathe or machine,

having a stationary head, B, secured upon it,

in which a hollow shaft, 0, is fitted, having a series of driving-pulleys, D,of different diameters, attached to it.

' Within the hollow shaft 0 there is placed a bar or lever, E, which works on a fulcrumpin, a. One end of this bar or lever has a curved arm, F, attached to it, through which "a set-screw, b, passes, and the opposite end has about arm,G, attached,which carries a cutter, H, said cutter being secured in the end of a stock, 0, attached to the end of thearm G by a pivot, d, and bearing,when at work,against a stop, 6, atthe end of the arm. The form or shape of the two arms F G is shownclearly in Fi 1.

%is an upright permanently attached to the bed A,and havinga tube, J ,fitted permanently in its upper end, said tube having a slot, f, in its upper surface, extending its whole length,

I and K is a screw which is fitted in the tube J and allowed to slide freely therein. On the tube J there is placed a pattern, L, which is allowed to slide on said tube, and is connected to the screw K by a pin or screw, 9, which passes through the slot f in the tube J, as shown clearly in Fig. 1. On the screwKthere -is'fitted a pulley, L, having an internal screwthread, into which the thread of the screw K fits.

M is a shaft which is fitted longitudinally in the bed A, and has a screw, g,cut on one part of it. This shaft is rotated bya belt, h, from the hollow shaft 0, and the pulley L is rotated by a belt, 2', from shaft M. (See'Fig. 1.)

. ,(N is a slide which 'is placed upon thebedA,

and has a circular plate, 0, fitted upon it.

The plate 0 is provided with apendent shaft,

P, which passes loosely through a sleeve, Q, at-

.tached to the slide N. The shaft P has a shoulder, j, on it,which projects a trifle below the sleeve Q, and against which a collar, R,

'bears, said collar having a worm wheel, S, at

its lower end,which gears into the screw 9 on shaft M. The Washer and nut are secured on shaft P by a nut. T- (See Figs. 1 and 3.)

The operation is as follows: In operating upon bayonets, the latter are secured one at a time to a support, U, on the plate 0, the neck k of the bayonet (shown in red in Figs. 1 and 2) being secured in such a relative position with the cutter H that the latter may rotate around it. as the shaft 0 is rotated. As the cutter rotates,the slide N is moved or fed along toward the head Bin consequence of the screw 9 gearing into the worm-wheel S on shaft 1?, the nut T being screwed up, so as to cause the collarR to press or bind firmly against the shoulder j on the shaft P. During this straight or rectilinear movement of the slideh the out ter H turns the-straight portion of the neck 76 ofthe bayonet,which is included between the socketl and the curve 121.. When the cutter reaches the curve m,the slide N comesin contact with stops at (one or more) on the bed A,

and the movement of the slide isstopped, and

turn the curved part m of the neck,which is a portion of a circle. At the commencement of the operation the hut T is screwed up sufficiently far to cause the collar R to bind against the shoulder'j of the shaft P to cause friction enough to prevent the plate O' being.

turned underthe action of the screw g;. but when the movement of the slide N is stopped the plate 0, it will be seen, must rotate, thev friction ofthe collar R against the shoulderj being overcome. The concave form of the neck It is produced by the pattern L,which is moved along on the tube J by the action of thenut-pulley L" and screw K, the pattern as it moves actuating the set-screw b, and consequently the bar or'lever E, which causes the cutter H to move inward or outward from the work, cutting theflatt'er of the desired form circumferenlially, in accordancewith the pat:

tern L. Thus it will be seen that the work is performed automatically, there being no manipulation required onthe part of the att'endant after the work is secured to the vsupport U and the driving power applied to the pulleys D.

LWe would remark that the speed of the movement of the pattern-L, as well as the speed of the rotation of the screw 9, and also the pitch of the latter,are regulated so as to be proportionate to the speed of the rotation of the cutter H; and we would further remark that the cutter H is attached to thepivoted stock a in order'to admit of the cutter turning backward, when necessary, withou-t marring the work.

We do not claim, broadly, the turningof irregular formsthrough the, medium of a pattern acting upon a cutter,-for patterns have been employed and arranged in various ways;

but,

Having thus described our invention, what we'doclaim' as new, and'desire to seeureby Letters Patent, 'is---- v I 1-. The rotary cutter H, attached to the bar or lever E, secured in the hollow shaftO of the driving-pulleys 1% in combination with the sliding pattern and sliding and rotating stock V, arranged substantially as and for the purpose herein set forth.

'2. The particular arrangement of the slide N, plate 0, with the stock V attached, and

shaft P, together with the collar R, wormed wheel S, and nutT on shaft 1?, and the sleeve Q, attached to slide N,with the stop at on the bed'A, for the purpose 'of ad'rnitting or producing the two movementsof the support U, asset forth.
